"One of the greatest problems in present-day Eucharistic celebration is the temptation to abandon the traditional explanations without proposing appropriate substitutions. It was easy to demolish the past, but explanations have not been suggested that might last longer. The solution of course is not to continue with the guidelines of the past, and beyond renewing exterior forms, we must add new vital sap. The form can change or remain the same, what is important is to have a new justification, with greater vigor and support."
